Subject: [PATCH v3 0/5] powernv: Enable Dynamic Frequency
Date: Thu, 20 Mar 2014 17:40:55 +0530 [thread overview]
Message-ID: <1395317460-14811-1-git-send-email-ego@linux.vnet.ibm.com> (raw)
From: "Gautham R. Shenoy" <ego@linux.vnet.ibm.com>
Hi,
This is the v3 of the consolidated patchset consisting
patches for enabling cpufreq on IBM POWERNV platforms
along with some enhancements. I have incorporated the review
for v2 (which can be found at [1]).
- This patchset contains code for the platform driver to support CPU
frequency scaling on IBM POWERNV platforms.
- In addition to the standard control and status files exposed by the
cpufreq core, the patchset exposes the nominal frequency through the
file named "cpuinfo_nominal_freq".
The changes from from v2:
- Updated the changelog for "powernv: cpufreq driver for powernv platform"
to record the fact that policy->cpus must be populated with a sibling mask
that includes even the offlined siblings.
- Dropped the patch named
"powernv:cpufreq: Create a powernv_cpu_to_core_mask() helper"
since the driver->get() method can use cpu_sibling_mask().
- Updated "powernv:cpufreq: Implement the driver->get() method" to
use cpu_sibling_mask() in powernv_cpufreq_get()
The patchset is based against commit 4907cdca7210c5895311bddcf05a4c85b67d8566
of the mainline tree.
